lmPRovEMENT IN sTovEs.

Specicatio'n foxmingvpart of Letters Patent No. 159,465, dated February 2, 1875 g application tiled June 20, 1874.

To all whom it may concern: y

Be it known that I, DAVID L. STILEs, of the city of Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Im provementin Stoves; and l do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, in which- Figure l is a sectional elevation. Fig. 2 is a bottom view. Fig. 3 is a cross-section.

This invention relates speciallyto the construction of wood-stoves. Such stoves have generally been made without a grate, and the wood has been placed directly in the bottom of the tire-chamber. The objection to this is, that the ashes accumulate in a body at the bottom, and obstruct the draft, and the Wood, being partially embedded in the ashes, is imperfeetly burned, and much loss of fuel ensues. The ashes are also difficult to clean out, and much dust is necessarily raised.

I employ in my stove a grate similar to a grate in a coal-stove, and also use an ash sink or pit, with a drawer therein for receiving the ashes, so that the draft is unobstructed at all timesthe wood burns clean, and the ashes are readily removed without dust.

These features are general, and are connected with my invention only in the purpose to which they are applied, viz.7 in a Woodstove instead of a coal-stove.

This invention consists in the combination, in a stove, of a base having the inwardly-projecting iian ge, with lugs thereon, to secure the journals of the grate, and vertically-projecting flanges to secure the casing and base to the stove.

A is the cylinder of an ordinary wood-stove. B is the base; O, the grate, and D the ashsink. The base and the ash-sink are made in two separate parts, and the ash-sink is attached on vthe under side of the base by bolting or otherwise, as shown in the bottom view, Fig. 2. A convenient means of attachment is by flanges or lugs, as shown. By thus making them separate instead of casting them both in one piece, as is usually done in coalstoves, they can be separated at any time, and

either part replaced without discarding the other part. The base is provided on t-he inside with a horizontal flange, a, located at the base of the nre-chamber, and inclosin g an opening, within which is located the grate O, which stands at about the same level as the iiange. The grate swings free in the opening, and has the bearings b b for its journals located on the flange a, as clearly shown in Fig. 3. This liange serves an important purpose in two ways: First, it serves as a ledge to support the wood which is placed in the lire-chamber, and thereby prevent such an accumulation of weight as might tilt the grate and let the wood down 5 and, second, it serves to throw the ashes inward toward the center, so that it will be sure to fall into the pan beneath without escaping around the sides.

In the respect rst named it is quite important in a wood-stove, since the pieces of wood are frequently short and of considerable weight, and, in being thrown into the stove and striking the grate, they would displace it. This is more apparent when it is considered that the sticks of wood are usually inserted endwise through the door, and the lower ends usually strike beyond the center of the grate.

The grate can be made smaller than ina coal-stove, since the combustion is more free and perfect, and the wood will burn perfectly beyond the surface of the grate, as no great accumulation of ashes will rest there, but they will fall through into the ash-sink.

The front end of t-he ash-sink is left open, and into this slides the ash-pan E. The pan ismade flaring at its sides, and of a size to ll the whole cross-area of the ash-sink. Its sides and ends, therefore, project inward and beyond the inner edges of the iiange, and are overlapped by the latter, and 'all the ashes will be discharged into the pan without escape at the sides, thus keeping the ash-sink clean. The front end of the ash-pan may have a guard or cover, which closes up against the open end of the ash-sink and shuts it, thereby preventing escape of dust into the room.

A wood-stove constructed as above described is more eective in action than those now in use.

A particular advantage in forming the base and ash-sink in separate parts is, that the flange a can thus be formed upon the base, which could not be it' the57 Were cast together.

The ash-sink can also be made of .larger area than the cylinder of the stove, which could not be if cast together.

The enlargement of the sink is desirable to enable a pan of larger size than the grateopening to be used.

I am aware that the fuel-supply chamber of a stove for burning coal has been bolted to a horizontal flange projecting from `the sides of the stove-casing; but such is not my invention.

Having thus described my invention, I do not claim a grate in a Wood-stove; nor do I Witnesses.
